"Conquering" a spa is only for a season. During that season, you can see an entire roster multiple times. Being a conqueror provides unexpected benefits like being able to see talent beyond regular spa hours, having options of earlier and later access, being offered "better" rooms, and booking favourites easier.
But there are always new girls coming into the spa, and you can't see them all, and soon there are originals you've come to appreciate, and new gems to discover. You can try to see all the new girls coming in, except now it's a new season where you don't know half the roster. You're seeing old and new, and deciding who to see next at the spa. You'll have a repore with the manager/mamasan/owner, getting first looks - the parade of new talent keeps on passing you by. Some of the old talent you've repeated with have moved on, and you're trying to figure out, "which spa are they at now?" or "have they left the industry all together?"
Some of the new talent is exceptional and immediate repeats. Others, not as much.
Then you realize there are more "conquerors" than originally thought, who are also sampling the new, and wonder who was conquered?
Did I conquer the spa, or did the spa conquer me?
